Abstract

Purpose: The aims of this study were (1) to assess the utility of the Quality of Life in Neurological Disorder (Neuro-QoL) questionnaire in patients with carpal tunnel syndrome by comparing the validated patient-reported outcome (PRO) measure Neuro-QoL to the validated Carpal Tunnel Syndrome Assessment Questionnaire (CTSAQ) before and following carpal tunnel release, (2) to compare the measurements of the median nerve cross-sectional area (CSA) using high-resolution ultrasound (HRUS) before and after surgery, and (3) to determine a correlation between HRUS and PRO. Methods: Individuals diagnosed with carpal tunnel syndrome were evaluated using the CTSAQ, Neuro-QoL, and HRUS before surgery and at 3 months after surgery. Results: Twenty patients completed the study. Overwhelmingly, there was an improvement in symptoms and function assessed by patients on both the Neuro-QoL and the CTSAQ at 3 months after surgery. The Neuro-QoL Physical Function and Upper Extremity scores had strong correlation with the CTSAQ activity score but had low to moderate correlation with the CTSAQ symptoms score, before and after surgery. The HRUS measurements of the median nerve at the carpal tunnel inlet demonstrated a decrease in CSA whereas no noticeable changes were observed at mid tunnel and at the outlet (hook of hamate). The correlations between the ultrasound findings and PRO measures ranged from weak to strong. Conclusions: Patients had resolution of symptoms and higher physical function following carpal tunnel release measured by both the CTSAQ and the Neuro-QoL scores. The Neuro-QoL self-assessment questionnaire, a measurement of quality of life, correlated well with the CTSAQ. Therefore, it could be used as a self-assessment outcomes tool in patients undergoing carpal tunnel release. At 3 months after surgery, HRUS measurements of the median nerve CSA showed a noticeable decrease of CSA only at the inlet of carpal tunnel. This objective improvement correlated with the improvement in CTSAQ and Neuro-QoL scores. Type of study/level of evidence: Diagnosis II.
